Well,  I don't yet know,  as I've not been able to build a bootable floppy 
image.
This is 1.98,  installed with --prefix=/usr/grub2 to avoid 
clashing with my production grub1 and I try this

 /usr/grub2/sbin/grub-install --root-directory=/mnt/dkt fd0

where I created a device map:

cat /mnt/dkt/boot/device.map
(fd0)     /dev/sdc

but the grub_install fails and a bash -x of it reveals,  near the end,

/usr/grub2/sbin/grub-setup --directory=/mnt/dkt/boot/grub 
--device-map=/mnt/dkt/boot/grub/device.map fd0
Invalid device `fd0'.

I copied my grub_install command exactly (other than the explicit path of the 
script) from the one shown in

http://www.gnu.org/software/grub/manual/html_node/Installing-GRUB-using-grub_002dinstall.html#Installing-GRUB-using-grub_002dinstall

In particular the device name of fd0.

Also the bash -x trace shows that elsewhere in the grub_install script, it did 
use my devicemap and did map fd0 to /dev/sdc (and in fact built a lot of files 
on the diskette).  But not bootable!

Can anyone help me build the bootable floppy?    Or does it have to be a CD?   
Or is there some other way I can try out your suggestion?
